HI @shalini_jha

You can try this as well!
composer require drupal/rat (RenderArrayTool (RAT))

Hi @bojanz
I have solved this issue and also created MR for RenderArray not found in inline entity form render.
Kindly review the changes .

Thank you.

composer require drupal/rat solves the issue but is it possible to add this dependency via ludwig?

Re: #6

Ludwig is not a proper place to add dependencies to other drupal modules. The .info file is a proper place for that.
See the related issue.
